CW3 INDIRECT COOLER INSTALLATION MANUAL | 9
INSTALLATION
DROPPER DETAILS
Cooler is supported by a 530 x 530mm (20 7/8” x 20 7/8”)
dropper with a minimum metal thickness of 1.0mm (20 gauge).
The dropper duct must have a raw edge or safe edge at the top.
Do not fold in a flange as this may interfere with the transition
and/or the Weatherseal
ILL2774-A
Cut a 50mm diameter cable exit hole in the dropper then fit and
screw the cable grommet into position. Locate the hole so the
cables will not interfere with the operation of the Weatherseal.

PREPARING THE TRANSITION
The cooler will be accompanied by a separate kit box containing
the dropper transition assembly, fittings and all associated
fasteners.
Begin by dismantling the dropper transition assembly on the
ground. For accessibility purposes, it is best to temporarily
remove both weatherseal flaps as shown.
ILL2775-A
Fit the transition onto the dropper, ensuring that it is orientated
correctly, as shown below.
Once level, secure the transition to the dropper using 6 (six) of
the supplied fasteners. There are 2 pilot holes on each side and
a single hole on the front and rear (centre) of the transition.

Transport the transition and dropper assembly to the roof.
